On Thursday, the East River Waterfront Esplanade officially opened to the public. Last week, while the paint on the new bike lanes was still drying, City Planning Commissioner Amanda Burden took AN on a walk through of the first section. The commissioner barely contained her excitement while showing off design details by landscape architect Ken Smith and SHoP Architects. Follow the commissioner as she takes us through the dog run and points out clever details like the “Get-Downs,” the riverside bar stools, and “seat walls.”
